Good Material Replacement | | Lubex Ion Chromatography Column Helps Phosphate Determination Experiment Reduce Costs and Increase Efficiency!
Date: 2025-12-12Read: 0
I bought a box of shrimp with excitement, ready to showcase my skills at home. After putting it in the pot, I was stunned: a plate full of water, the shrimp had shrunk into shrimp pellets, and the taste was woody and had a sour taste
Don't doubt your cooking skills, what you may encounter is the 'Phosphate Preserved Shrimp' exposed at this year's 315 Gala.
In order to make the shrimp more plump and weighed, some merchants may overuse phosphate. butAccording to GB 2760-2024 "Standard for the Use of Food Additives"The usage of phosphate (calculated as phosphate ions) in frozen shrimp should not exceed 5.0 grams per kilogram!
Long term excessive intake of phosphate can disrupt the balance of calcium and phosphorus in the human body, increasing health risks. Therefore, accurate detection of phosphate content in food is a key link in ensuring food safety.
According to GB 5009.256-2025 "National Food Safety Standard - Determination of Multiple Phosphates in Food", the core of the detection depends onHigh capacity hydroxide selective anion exchange column.
However, in the past, the market price of imported chromatography columns and protective columns, which were the core of this laboratory configuration scheme, often approached 25000 yuan.The high cost of testing exacerbates the already struggling laboratory.
Faced with this pain point,Guangzhou Green Hundred Herbs launches LBC11 anion analysis column
On the premise of meeting national standards, it can quickly and accurately detect various phosphates, while reducing costs by half, providing more sincere choices for experimental testing units.

Separation effect spectrum
At a concentration of 0.3 mg/L, phosphate ions (PO ₄³ ⁻), pyrophosphate, tripolyphosphate, and triphosphate all achieved ideal results with sharp peaks and baseline separation.
